The cell membrane! also known as the plasma membrane. It is about 8 nm thick, and all cells have one! It is a semipermeable lipid bilayer. This means that it does not let all materials pass through it, generally only ones that are small and do not have a significant charge. The bilayer consists of phospholipid molecules where the phosphorus heads turn towards the outer environment and inner environment, and the hydrophobic lipid tails turn in towards each other. The membrane may also have membrane proteins that may be either integral or peripheral, and cholesterol molecules. There may be filaments and tubules that help support the cell in the extra cellular matrix. Some cells may have a cell wall that surrounds their cell membrane.

What are greenhouses used for?
